Rajon Rondo is arguably one of the best point guards in the league, and one of the main reasons he is so good, is because of his craftiness with the basketball. When he attacks the basket he almost always uses a fake of some sort to get the defender off balance or out of place. This is one of the basketball fundamentals for finishing around the basket off of a pivot move.
This move is the advanced version of the Rondo fake, it is used when the defender doesn't quite bite on the first move, and you must use another fake before getting your shot off. Watch this video to learn how to do a rondo fake, and also get some tips to making the move work for you. Whether you use this move in a game or not it is still good for working on your footwork and being under control when you drive the basketball.
